(6) ethernet segment mark (Ethernet Segment Identifier, ESI) is the company of PE equipment and a certain CE
The unique identification for connecing definition, for identifying the interface connecting in PE equipment with a certain CE.
(7) multi-home networking, i.e., the networking that same CE equipment is connect with multiple PE equipment respectively, wherein multiple PE equipment
The ESI of the upper same CE equipment of connection is identical, and the ESI for connecting different CE equipment is not identical.
The disclosure is applicable in the multi-home networking based on EVPN VPLS, event occurs mainly for message forwarding path
The problem of how updating forwarding-table item when barrier, provides a solution.
It is worth noting that, at present in the multi-home networking based on EVPN VPLS, due to the forwarding table of PE plant maintenance
Middle record has the corresponding outgoing interface information of the MAC Address learnt on each VSI, each MAC Address, therefore, it is forwarded in message
In the case that path is broken down, it is corresponding that PE equipment will usually update each MAC Address relevant to the path broken down
Outgoing interface information, still, if MAC Address relevant to the path broken down is more, then turning being updated using aforesaid way
When delivering, the corresponding outgoing interface information of each MAC Address is updated, causes the time expended more, so that forwarding table update is too late
When, lead to not switch forward-path in time.
Illustratively, in the dual-homing networking shown in fig. 1 based on EVPN VPLS, PE equipment 1, PE equipment 2 and PE are set
EVPN VPLS business is configured in standby 3, PE equipment 1 and PE equipment 2 establish EVPN peer, and PE equipment 1 and PE equipment 3 are established
EVPN peer, CE equipment 1 is connect by way of VPLS AC with PE equipment 1, CE equipment 2 by VPLS AC mode respectively with
PE equipment 2 and PE equipment 3 connect, and the ESI for the interface configuration that PE equipment 2 and PE equipment 3 are connect with CE equipment 2 respectively is ESI1,
It forms 2 dual homed of CE equipment and belongs to PE equipment 2 and PE equipment 3, likewise, CE equipment 3 can also be distinguished by way of VPLS AC
It is connect with PE equipment 2 and PE equipment 3, the ESI for the interface configuration that PE equipment 2 and PE equipment 3 are connect with CE equipment 3 respectively is
ESI2 forms 3 dual homed of CE equipment and belongs to PE equipment 2 and PE equipment 3.
In above-mentioned networking, under normal condition, the message forwarding path between CE equipment 1 and CE equipment 2 has two, i.e. CE
The message of equipment 1 reaches CE equipment 2 by PE equipment 1 and PE equipment 2 (i.e. public network path 1), the message of CE equipment 1 is set by PE
Standby 1 and PE equipment 3 (i.e. public network path 2) reaches CE equipment 2, and the message forwarding path between CE equipment 1 and CE equipment 3 also has two
Item, the i.e. message of CE equipment 1 reach CE equipment 3 by public network path 1, the message of CE equipment 1 reaches CE by public network path 2 and sets
Standby 3.In this case, outgoing interface information corresponding to the MAC Address learnt on each VSI in the forwarding table of PE equipment 1, packet
Include the mark in public network path 1 and the mark in public network path 2.
So, in the case where 1 failure of public network path between PE equipment 1 and PE equipment 2, PE equipment 1 can not pass through public affairs
Network diameter 1 E-Packets to PE equipment 2, therefore the corresponding outgoing interface of MAC Address that PE equipment 1 needs to learn on each VSI
Information is updated to " mark in public network path 2 " by " mark in public network path 1 and the mark in public network path 2 ".
Alternatively, PE equipment 1 passes through 1 turn of public network path in the case where link failure between PE equipment 2 and CE equipment 2
Text transmit messages to PE equipment 2, then is E-Packeted this message forwarded to CE equipment 2 by PE equipment 2 by the interface that ESI1 is identified
Forward-path is unavailable, and in this case, PE equipment 1 needs the MAC Address for learning the interface on each VSI by ESI1
Corresponding outgoing interface information is updated to " mark in public network path 2 " by " mark in public network path 1 and the mark in public network path 2 ".
Forwarding table is updated using aforesaid way, due to the quantity of MAC Address relevant to the path broken down, is influenced
The update efficiency of forwarding table, MAC Address relevant to the forward-path to break down is more, and the update efficiency of forwarding table is lower,
The time for needing to expend is more, so that forwarding table updates not in time, leads to not switch forward-path in time.
In view of the above problems, the disclosure provide solution in, by forwarding table by MAC Address and VSI, ESI
It is associated, and the corresponding relationship between VSI, ESI and outgoing interface information is recorded, subsequent, if detecting, message forwarding path goes out
Existing failure, then can directly adjust outgoing interface information corresponding with the associated ESI of the message forwarding path to break down, without
It needs for the corresponding outgoing interface information of each MAC Address to be adjusted separately, forwarding table renewal process and VSI, ESI are associated
The number of MAC Address is unrelated, so as to promote the update efficiency of forwarding table, switches forward-path in time.
In the following, in conjunction with specific embodiments, the forwarding table updating method provided the disclosure is described in detail.
It is that a kind of framework for multi-home networking based on EVPN VPLS that the embodiment of the present disclosure provides shows referring to described in Fig. 2
It is intended to.In the multi-home networking, only in website 1 any one CE equipment and website 2 in any one opposite end CE equipment it is logical
Cross the message forwarding path of service provider network (i.e. public network) to illustrate, certainly, in the multi-home networking also
It may include the message forwarding path between other CE equipment and opposite end CE equipment, in Fig. 2 and be not entirely shown.Wherein:
CE equipment in website 1 connects the PE equipment of one end in service provider network by way of VPLS AC；The PE
Equipment pass through respectively PW1, PW2 ..., PWn peer end of the connection PE equipment 1, opposite end PE equipment 2 ..., opposite end PE equipment n, and with it is each
Opposite end PE equipment establishes border gateway protocol (Border Gateway Protocol, BGP) neighborhood；Opposite end PE equipment 1,
Opposite end PE equipment 2 ..., opposite end PE equipment n be separately connected the opposite end CE equipment in website (site2), wherein each opposite end PE equipment
The interface of peer end of the connection CE equipment is identified as same ESI.
The opposite end CE in CE equipment and website 2 in the case that networking shown in Fig. 2 is in normal condition, in website 1
Message forwarding path between equipment has n item, and load balancing forwarding can be carried out between this n paths.Wherein, PE equipment and right
It holds between PE equipment there may be P equipment (not shown), the disclosure does not limit this.
Under the network architecture of multi-home networking shown in Fig. 2, PE equipment can execute forwarding table as shown in Figure 3 and update
Method includes the following steps:
Step 301, the message for obtaining ESI respectively from the PE equipment of at least one opposite end, being forwarded by the interface of ESI mark
The MAC Address of middle carrying.
In the embodiment of the present disclosure, PE equipment can be transmitted between each opposite end PE equipment that bgp neighbor relationship has been established
EVPN routing, so as not to which between same PE equipment MAC Address can be learnt by control plane.
In a kind of possible embodiment, PE equipment can receive the MAC/IP that at least one opposite end PE equipment is sent respectively
Reachable the information of address notification routing, to obtain ESI, the MAC that carries in the message that the interface identified by each ESI forwards
Location.Wherein, MAC/IP address notification routing (MAC/IP Advertisement Route) is one of EVPN routing, such
The routing of type can be used for the reachable information from local end PE equipment to the address MAC/IP of other PE equipment publication unicast.
Specifically, in the reachable information for the MAC/IP address notification routing that each opposite end PE equipment is sent, including but it is unlimited
The MAC Address carried in the message that ESI, the interface identified by each ESI forward.ESI indicates that opposite end PE equipment connects
The mark of the interface of opposite end CE equipment, opposite end PE equipment can by ESI identify interface from opposite end CE equipment receive or to
Opposite end CE equipment sends message, learns the MAC Address carried in message, and the message learnt is indicated to PE equipment.
Step 302, the ESI based on acquisition, MAC Address, the corresponding VSI of each MAC Address and outgoing interface information, are forwarding
The corresponding relationship between VSI, ESI, outgoing interface information is recorded in table.
In some embodiments of the present disclosure, can ESI and MAC Address, the corresponding VSI of each MAC Address based on acquisition,
The MAC Address of the identical VSI of correspondence is divided in the same MAC Address set, and identical ESI will be corresponded in MAC Address set
MAC Address be divided in the same MAC Address subset.Further, the corresponding VSI of MAC Address subset based on division and
The outgoing interface information of each MAC Address in ESI, MAC Address subset can record VSI, ESI, outgoing interface information in forwarding table
Between corresponding relationship.
In specific implementation, PE equipment can be routed by receiving the EVPN that PE equipment in opposite end is sent, and be learnt on different VSI
The MAC Address of message can also be E-Packeted by local, learn the MAC Address of message on different VSI.For same
The MAC Address learnt on VSI can be divided in the same MAC Address set.Also, in the process of study MAC Address
In, the incidence relation between ESI and MAC Address can be identified by step 301, therefore, it goes to school for PE equipment in each VSI
The MAC Address of the identical ESI of correspondence can be divided in the same MAC Address subset by the MAC Address set practised.
Illustratively, it is assumed that VSI1 corresponds to MAC Address set 1 in PE equipment, VSI2 corresponds to MAC Address set 2 ...,
VSIa corresponds to MAC Address set p, also, PE equipment is routed by receiving the MAC/IP address notification of opposite end PE equipment, is identified
ESI1 is associated with the MAC Address subset 1 in MAC Address set 1, and the MAC Address subset 2 in ESI2 and MAC Address set 1 is closed
Connection, and so on, ESIb is associated with the MAC Address subset p 2 in MAC Address set p, wherein a indicates PE in multi-home networking
The total quantity of the type for the VSI that equipment has, b indicate the sum of the type for the interface that PE equipment in opposite end is connect with opposite end CE equipment
Amount.According to above-mentioned example, available corresponding relationship as shown in Table 1:

| VSI 1 | ESI1 | MAC Address subset 11 |
| VSI 1 | ESI2 | MAC Address subset 12 |
| VSI 2 | ESI3 | MAC Address subset 21 |
| VSI 2 | ESI4 | MAC Address subset 22 |
| … | … | … |
| VSIa | ESIb | MAC Address subset p 2 |
In the embodiment of the present disclosure, after determining the corresponding VSI and ESI of each MAC Address subset, since PE equipment is tieed up
Record has the corresponding outgoing interface information of each MAC Address in the forwarding table of shield, then, record can also be increased newly in forwarding table
Corresponding relationship between VSI, ESI, outgoing interface information.
In a kind of possible embodiment, the first list item being made of VSI and ESI can be recorded in forwarding table, and really
Fixed each matched MAC Address subset of first list item, and then based on each MAC in the matched MAC Address subset of the first list item
The outgoing interface information of location is recording the corresponding pass between the first list item and the second list item being made of outgoing interface information in forwarding table
System.
Wherein, the outgoing interface information of PE equipment may include the chain road sign between PE equipment and next-hop opposite end PE equipment
Know, i.e. PW mark, in addition, the outgoing interface information of PE equipment can also include the mark used when PE equipment is communicated with local terminal CE equipment
Label and port numbers etc., the disclosure does not limit this.
Illustratively, Fig. 2 shows networking in, under normal condition, the message forwarding path of PE equipment includes n item, i.e.,
By PW1, PW2 ..., the public network link of PWn mark can reach respectively opposite end PE equipment 1, opposite end PE equipment 2 ..., opposite end PE sets
Standby n, then, PE learning equipment to the corresponding outgoing interface information of MAC Address include public network link mark, i.e. PW1, PW2 ...,
PWn.The example for continuing to continue to use table 1, using VSI and ESI as the first list item, using outgoing interface information as the second list item, turning
Deliver corresponding relationship shown in recordable table 2:
Table 2
It is to be appreciated that the outgoing interface information that second list item records in table 2 is only as an example, and in practical application, second
The outgoing interface information recorded in list item can also include label and port numbers etc. that PE equipment uses when communicating with local terminal CE equipment,
The disclosure does not limit this.Also, in addition to recording above-mentioned first list item and the second list item, being matched with the first list item in forwarding table
MAC Address subset except, can also include other contents in table, the disclosure not limit this.
It is subsequent, it can be E-Packeted based on the list item recorded in forwarding table, it, can be with for example, after receiving message
The target MAC (Media Access Control) address carried in identification message, judges that the target MAC (Media Access Control) address matches with which VSI and which ESI, that is, determines
With matched first list item of the target MAC (Media Access Control) address, and then corresponding second list item of the first list item, i.e. outgoing interface information are determined,
It E-Packets in corresponding outgoing interface information.
The first list item constituted by increasing VSI ESI newly in forwarding table, the first list item is corresponding with MAC Address subset,
First list item is also corresponding with outgoing interface information, in this way, PE equipment when E-Packeting, can be carried by identification message
MAC Address subset belonging to MAC Address determines matched first list item, and then determines matched outgoing interface information, to realize
The purpose of unicast forwarding grouping.
Above-mentioned steps 302 are accepted, may further be executed:
If step 303 detects that the message forwarding path between PE equipment and opposite end CE equipment breaks down, adjustment pair
